I'm having an issue with my fuel gauge. When I turn the key on, it pins past full. I disconnected the sending unit wire and it still pins past full. The temp, and oil pressure gauges work fine. I have a new up graded voltage limiter. and the wiring harness to the rear of the car is a new year one repro. The wires on the gauge are connected properly. The gauge has never been removed from the cluster. Every other electrical component is working properly. Any thoughts??????
